S&S Cycle 06-12 Dyna 4-1/8in Bore Front Head Assembly

If you're rebuilding the top end of your 2006-2012 Dyna motorcycle, a solid front head assembly is crucial for getting your engine running right. This S&S Cycle front head assembly is built to the stock bolt pattern, meaning it'll install cleanly onto your existing engine case. It's designed with a 4-1/8 inch bore, which is a key measurement for ensuring proper piston fit and compression.

This head assembly is constructed from durable steel, measuring .585 inches thick, which provides a strong foundation for your engine's performance. It comes without a compression release, so if your original setup used one, you'll need to account for that during your build. S&S Cycle is a well-known name in performance V-twin engines, and this part reflects their commitment to well-built components for riders who demand reliability and performance from their machines.

When undertaking a top-end rebuild, always refer to your service manual for specific installation procedures and torque specifications. This part is not CARB approved and cannot be shipped to California.
